Laser Surgery for Glaucoma: Pros and Cons
Laser surgery uses a very focused beam of light to cut, break down, or destroy tissue. Doctors use laser surgery when medicines fail to control vision loss caused by glaucoma. Laser surgery is done more often than conventional surgery for glaucoma. But repeated laser procedures can lead to scarring.
The major advantages of laser surgery over conventional surgery for glaucoma include:
The most common complication from laser surgery for glaucoma is increased pressure within the eye. The pressure may be normal immediately after laser surgery but then may rise sharply within 1 to 4 hours, especially in people who have severe glaucoma. The doctor may give you eyedrop medicine before and after surgery to prevent this complication. Other complications may include:
Before laser surgery, medicine to numb the eye may be applied to the eye directly (topical anesthetic) or injected behind the eyeball (retrobulbar anesthesia). Some people feel a sensation of heat in the eye during laser surgery.
The main disadvantage of laser surgery for glaucoma is that it may not always lower pressure in the eye.
